ABSTRACT:
A shift assist apparatus for a marine drive includes a tube having a pair of biased springs, between which a sleeve at the end of a transmission cable is movably retained. A remote control cable is fixedly attached to the tube. High transmission cable shift forces associated with resistance to shifting cause the sleeve to move against the bias of one of the springs. A sensor detects this movement and sends an electrical signal to interrupt the engine ignition circuit, thereby preventing the firing of one or more cylinders of the engine. The interruption of the engine ignition reduces the torque on the shift mechanism, in turn reducing the shift forces in the transmission cable and enabling the operator to shift the transmission. When the shift operation is completed, the engine resumes normal firing.
